Technical field

This patent disclosure relates generally to the structure being made up of plastics at least partially, particularly relate to the furniture that can comprise molded plastic part, for instance desk and chair.

Background technology

As we all know there are many different types of desks and be used to multiple different purpose. Such as, conventional table can include the lower limb being pivotally attached to desktop, and lower limb can fold from the outward extending use position of desktop and lower limb at lower limb and move between the storage position being adjacent to desktop. The conventional table with relatively large desktop and folding leg is commonly called " banquet table ", and these desks usually in auditorium, banquet hall, conference centre, hotel, school, church and a great number of people party other places use. The desk of these types often has various different structure and uses under various configurations. When being no longer necessary to banquet table, table leg can move to storage position and desk can be easier to mobile or storage.

Because most of banquet table length are between 6 to 10 feet, width is between 3 to 4 feet, even if therefore lower limb is in folding position, the storage area needed for this desk is also quite big. So big storage area is problematic as commercial location or mechanism (such as hotel, school and church), because considerable this desk must be stored.

Conventional table often includes the desktop being made up of various materials (such as timber, particieboard or metal). But, often relatively heavy by timber, particieboard or metal desktop, and this can make table awkward or be difficult to mobile. And this desktop also of a relatively high by timber or metal desktop cost generally must be processed or polished before the use. Such as, timber make desktop and generally must obtain sand milling and colouring, and metal desktop must be formed required form and be painted. Further, since these are wooden and metal desktop is relatively heavy, desk transport and the cost transported therefore can be increased. The weight of desktop makes desk more be difficult to mobile and storage.

In order to reduce the weight of conventional table, desktop can be made up of the material (such as plastics) of relative lightweight. Disadvantageously, the desktop being made up of light material may require that big stiffener or other structure members (such as support, support, supporting member, etc.) are to strengthen desktop. Although these optional features can increase the intensity of desktop, but optional feature also can increase the weight of desk. These optional features can cause manufacturing cost to increase and need the extra time to assemble desk. Furthermore, it is necessary to these parts are assembled and are connected on desk by extra securing member, this is also required to the extra time and artificial in the fabrication process. Optional feature and securing member can increase the cost of desk further and make desk more be difficult to manufacture. And, these optional features and securing member have the lower limb of possibility injury user or the sharp edges of arm.

Conventional table can include the framework being connected with desktop. Framework can include a pair sidebar utilizing securing member to be connected with desktop side. Multiple securing member is needed to make framework and desktop be fixedly linked and the power being applied to desktop is delivered to framework. Undesirable, when applying relatively large load or power on some existing desks, framework can bend, deforms and/or separate with desktop. It addition, be likely to be separated or detached from desktop to the securing member of desktop for connecting framework. If load or power exceed certain value, securing member even can damage and tear desktop. The folding it addition, the framework of some existing desks or securing member can collapse in some cases.

If relatively large load or power are applied in a part for desktop, the desktop of some existing desks is it can also happen that undesirable bending or deformation. Such as, if load or power are applied to the outer part of regular desktop, then that part of desktop is it may happen that undesirable movement or bending. Specifically, that part of desktop is likely to downwards when load or power are applied to the upper surface of desktop.

The large scale of conventional banquet table needs manufacturer, retailer and consumer to provide substantial amounts of memory space. And substantial amounts of memory space is for having storage, transport and/or displaying especially individual problem the manufacturer of demand of many desks, retailer and consumer.

Summary of the invention

It is thus desirable to provide a kind of desk to overcome or alleviated by drawbacks described above and problem.

On the one hand, a kind of desk can include desktop and one or more lower limb, and described lower limb is sized and configured at surface (such as floor or ground) upper support desktop. This desk can also include framework and the lower limb being connected with framework. These lower limbs can move between folding or storage position and extension or use position relative to desktop. Specifically, these lower limbs can pivot between the outward extending extended position of desktop in the folding position of at least contiguous desktop lower surface arrangement of lower limb and lower limb. If it is required, when lower limb is in folding position, lower limb can contact or the lower surface of adjacent desktop at least partly. It addition, the lower surface of desktop can include one or more recess, it is sized for and is formed at when lower limb is in folding position and hold at least some of of lower limb. Advantageously, so can reduce storage and/or transport the space needed for desk.

On the other hand, a kind of desk can relative lightweight, desk so can be made to be easier to transport and mobile. Such as, desk can include contributing to the lightweight table top that reduces desk gross weight. Desk can also be made up of parts few in number or assembly, so can reduce the weight of desk. Furthermore, it is necessary to securing member few in number assembles desk, the weight of desk so can also be reduced. These securing members few in number can also make desk rapidly and easyly be assembled.

On the other hand, a kind of desk can include the desktop that is made of plastics. Such as, desktop can be adopted blowing, injection moulding, rotary molding or other suitable molding processes to make by molded plastics. Molded plastics desktop can provide relatively hard and high intensity structure, so can bear using and wearing and tearing repeatedly. The manufacture of molded plastics desktop is also relatively rapid, easy and efficient. It addition, molded plastics desktop can easily be molded as required size and dimension, for instance universal table, bidge table, personal table etc. Molded plastics desktop can relative lightweight, for instance because it can include the empty internal formed in molding process. Molded plastics desktop can also include that interval is less constant and/or two relative walls of preset distance, so can aid in the strength and stiffness improving desktop. It addition, molded plastics desktop generally can have weatherability and to temperature-insensitive. Additionally, molded plastics desktop will not get rusty or occur other to deteriorate by burn in the persistent period, so can aid in and form durable desk.

On the other hand, a kind of desktop can be made up of molded plastics and one or more feature is integrally formed in the molding process of the part as whole Construction integration. Such as, molded plastics desktop can include one or more recess (being also referred to as " recessed conjunction portion (tack-offs) ") and these recesses can be designed and be positioned to the intensity improving desktop and/or the wall interconnection making desktop spaced apart. These recesses can also be sized and configured to form the structure with special characteristics and quality, for instance desktop has substantial uniform intensity, rigidity and/or structural intergrity. Molded plastics desktop can also include other features, for instance improves the structure of at least one of intensity of desktop, rigidity and/or torsion resistance.

On the other hand, a kind of desk may be configured to obtain the parts of quick and convenient manufacture. Such as, the manufacture of the sidebar of lower limb and/or framework can be relatively easy. It addition, the sidebar of lower limb and/or framework can rapidly and easily connect on the table, manufacturing cost so can be reduced. Desk only can also be made up of a small amount of parts and need securing member few in number, so makes desk rapidly and easily can be assembled by manufacturer, retailer and/or consumer.

On the other hand, a kind of desk can so that the stacking of multiple desk. Advantageously, the desk stacked can be arranged to the configuration of alignment. Such as, a desk can align with adjacent tables easily, is so easy to the transport of multiple desk, storage and/or display. It is essential that the desk of alignment can be in transport, storage or the state such as display according to such as desk and vertical, level or become suitable angle to arrange. If it is required, the desk stacked can interlock or have the tendency kept together. Such as, between the desk of adjacent one another, frictional fit or interference engagement can be tended to make desk keep being in stacking configuration. If desk has the tendency kept together, then this may consequently contribute to reduce damage to desk in transport, storage and/or display process.

On the other hand, a kind of desk can the space that with reduction take nested with adjacent tables. It is essential that the desk of nesting makes these desks can be stored in less area, storage and cost of transportation so can be significantly reduced. Nested desk can also store greater number of desk under the area identical with the conventional table not nested together. It addition, the desk of nesting can aid in protection desk from damage. Such as, owing to the top of a desk can be arranged within the bottom of adjacent tables, therefore can aid in and prevent desk to be damaged. Nested desk can also have the desktop of identical with conventional table or substantially the same size, so can show that these desks can have similar outward appearance and characteristic to consumer, for instance intensity, structural intergrity etc. Nested desk can also have the footprints identical with conventional table, but the desk of nesting substantially can have more desk to be arranged on tray or in container, and/or the desk of equal number can be had to be arranged in the space that may be significantly smaller.

On the other hand, a kind of desk nested with adjacent tables can be in and stack configuration. Advantageously, nested desk can have the height of substantially reduction compared with the conventional table not nested together. Such as, existing desk can have the height that highly can stack at least 63.75 inches for the desktop of about 2.125 inches and 30 so existing desks. The illustrative embodiments of nested desk can have the desktop of about 2.0 inches of thickness, but can be overlapping with adjacent tables about 0.25 inch so that the height of the overlapped section of nested desk is only about 1.75 inches. Therefore, the height of 30 nested desks is reduced to about 52.75 inches, because adjacent tables can nest together. Specifically, can be arranged in adjacent tables due to a part for desk or overlapping with adjacent tables be in nested arrangement, the total height of nested desk therefore can be made to be reduced. Therefore, in this representative configuration, the height being in the desk of nested arrangement can simply be about 1.75 inches. Thus, before the aspect ratio of each nested desk, existing desk reduces about 0.375 inch to 0.25 inch. More desk layout so can be had to be in and to stack configuration, thus substantially increasing the quantity that can overlay on tray or shelf or be arranged in the desk in container or truck.

On the other hand, a kind of desk can nest together to reduce the total height stacking desk with adjacent tables. Such as, conventional table can have the blow molded plastic desktop of highly about 2.0 inches and the framework of highly about 1.625 inches. The height of the framework of this conventional table has the desk of desirable strength and rigidity more than the 80% of height of table top to be formed. Framework for this conventional table can have rectangular cross sectional configuration, so contributes to forming girder structure by two opposite wall of the less constant distance in interval. It is known that the reduction of frame height can cause the reduction of desk intensity. It is also known that the reduction of frame width can cause that undesirable distortion and/or bending occur desk. Compared with these existing desks, framework makes nested desk can have the total height identical with conventional table and an outward appearance, and the overall strength identical with conventional table and structural intergrity, but makes desk to nest together. Consumer so can also be made to infer immediately, and nested desk has the overall strength identical with conventional table, rigidity and torsion resistance, because these desks can have substantially the same size and footprints. But, the framework of nested desk significantly reduces two or more height stacking desk. Owing to nested desk can have significantly reduced height under nested arrangement, therefore can saving considerable space, this point is extremely important to manufacturer in manufacture and transportation; In storage or retailer is extremely important when displaying multiple desk; And/or the consumer buying, transport or store multiple desk is also extremely important.

On the other hand, a kind of desk can be sized and configured to nested with at least one other desk so that the height reduction of nested desk is more than 10%. Such as, the height of single desk can be about 2.0 inches. When desk is nested with other desks, the height of about 1.75 inches only contributed by this desk, because a part for desk nests together. In this embodiment, nested desk causes each about 0.25 inch of height reduction stacking desk. Therefore, it is in the aspect ratio of the desk stacking configuration and is in that non-to stack configuration little by about 12.5%. Advantageously, desk is so made can more efficiently to be stored, transport and display, since it is desired that less space. In another embodiment, standard pallet or transport configuration can include 21 conventional table, but the desk with telescoping feature disclosed herein can allow 27 or 29 desks to be arranged in standard pallet or in typical transit structure. If arranging 27 rather than 21 desks on tray or in standardised transportation structure, then can store more, transport or display the desk of substantially 28%. If arranging 29 rather than 21 desks on tray or in standardised transportation structure, then can realize desk quantity and improve 38%. Advantageously, this can cause saving significantly on and cost advantage, because such as can storing under equal area, transporting or display significantly more desk; Or at the desk to storage under the area of when young 25%, transport or display equal number. When substantial amounts of desk such as obtains transporting in standard or high power capacity container, can cause greatly saving cost and there is cost advantage.

On the other hand, a kind of desk can be nested with adjacent tables so that the height reduction substantially 20% of nested desk. Such as, the height of conventional blow Plastic table top is usually 2.0 inches or bigger. The height of table top of nested desk is about 2.0 inches when it is not nested with another desk, but the height of desk overlapped section is only about 1.5 inches to 1.75 inches when nested with another desk. So causing when two or more desks nest together, highly significant reduces by 12.5% to 25%. Specifically, if nested table height reduces about 20%, then these desks can have the height of about 1.6 inches when being in nested arrangement. Additionally, nested desk can have the weight of the conventional table less than contrast. Therefore nested desk can contribute less weight when stacking with other desks one or more or be nested, so can stack more nested desk when not increasing additional weight.

On the other hand, a kind of desk can include accommodation part on the top of desktop, for instance groove, raceway groove or recess, is sized for and is configured to the part holding adjacent tables so that the nesting of desk. Such as, accommodation part can be arranged in upper surface and/or the periphery of desktop. More specifically, accommodation part can have generally L-shaped structure, simultaneously lower surface is substantially parallel to the upper surface of desktop and sidewall is essentially perpendicular to the upper surface of desktop. A part for adjacent tables can be arranged in accommodation part so that desk can nest together. Specifically, a part (such as protuberance or flange) for framework and/or a part (such as edge or table angle) for desktop can be arranged in accommodation part. More specifically, a part for the sidebar of framework is being held in part along the side arrangement of the desk of adjacent one another. The bottom of flange part and/or the table angle of desktop can also be arranged in the accommodation part of desk of adjacent one another.

On the other hand, a kind of desk can include being suitably sized to and be configured so that the framework that desk stacks.

The top of framework can be arranged in the framework accommodation part of the bottom of desktop and this may consequently contribute to make framework be maintained at desired location. Framework can also include the bottom being sized and configured to the top of the desk of contact adjacent one another. Framework can also include the bonding part being sized and configured to be arranged in the accommodation part of adjacent nested desk. Bonding part can include the flange or the protuberance that downwardly extend, is sized for and is configured to mate in the accommodation part (such as groove or otch) of adjacent nested desk. Advantageously, under nested arrangement, framework can directly support at least some of of the weight being applied on desk and/or power, so contributes to preventing desk to be damaged. Such as, when desk stacks and is in horizontal arrangement, the framework of a desk can pass through to make the table support major part weight stacked in order to avoid the mode damaging desk contacts the desk of adjacent one another. So can arranging 10 under stacking configuration, 20,30 or more desk, without producing to damage to any desk. If it addition, the bonding part of framework is arranged in the accommodation part of adjacent tables, then stacking, store and/or transporting of desk can be easy to, stack configuration because can aid in keep being in by these desks and guarantee that weight obtains suitably and/or is uniformly distributed.

On the other hand, a kind of desk can be sized and configured to nested with the desk of adjacent one another, and wherein weight or load are supported in multiple regions, at diverse location and/or by different surfaces. Advantageously, multiple contact areas can make stress and power be distributed in more in large area and may consequently contribute to prevent desk to be damaged. Such as, desk can include being sized and configured to one or more contact areas of the upper surface contacting adjacent desktop. More specifically, the sidebar of framework can include the bottom of substantial parallel layout with the upper surface of desktop, for instance flat surface. It addition, the sidebar of framework can include bonding part, for instance the flange downwardly extended or protuberance, it is sized for and is configured to be arranged in the accommodation part of desk of adjacent one another. The bottom of flange can contact the lower surface of accommodation part. It addition, desk can include other parts, for instance table angle or flange part, it is sized for and is configured to be arranged in the accommodation part of adjacent one another desk. Such as, table angle and/or flange part can include the compressed edge of the lower surface of contact accommodation part. When two or more desks nest together, multiple contact areas can so that the stacking without scratching or damaging desk of desk.

On the other hand, a kind of desk can include the desktop with the one or more parts being made up of extrusion molded plastic. Such as, a part for table angle and/or flange part can be formed in blow-molding process in compression moulding. Advantageously, compression moulding table angle and/or flange part can aid in the structure forming rigidity firmer, bigger and/or bigger impact resistance, so can improve life-span and the practicality of desk. It is essential that the part that compression moulding can make an angle and/or flange part is relatively thin because between the wall of extrusion molded plastic structure almost without or any gap useless or space. Compression moulding table angle and/or flange part can also be sized and configured to coordinate in the accommodation part of the desk of adjacent one another, so can so that the stacking with nested of desk. Compression moulding part can also be sized and configured to a part for contact framework. Such as, compression moulding part can be able to contact or adjacent compression moulding part along the sidebar of at least some of layout of flange part and framework, so can aid in and framework is positioned and retained in desired location.

On the other hand, a kind of desk can include compressed edge. Such as, if desktop is made up of blow molded plastic, then compressed edge can be formed by the outer wall folded to itself so that the twice of compressed edge thickness substantially outer wall thickness. Compressed edge can be made by any suitable mode. Compressed edge can be arranged around all or part of girth (such as edge and/or table angle) of desktop. Advantageously, compressed edge can aid in raising intensity, rigidity, structural intergrity and/or impact resistance. Compressed edge can also be sized and configured to be at least partially disposed in the accommodation part of adjacent nested desk.

On the other hand, a kind of desk can include having various sizes of compressed edge. Such as, the table angle of desktop can include the compressed edge different from along the side of desktop and/or the compressed edge size of end extension. Specifically, desktop can include the flange part that downwardly extends and table angle can include highly being substantially equal to or greater than the compressed edge of flange part major part height. Table angle can also include highly generally or be substantially equal at least the compressed edge of flange part height. The side of desktop can include the compressed edge less than the compressed edge at table angle. Such as, the side of desktop can include the compressed edge that is highly substantially equal to or less than flange part height. The height of the compressed edge arranged along side and/or the end of desktop can also may be significantly smaller than the height of flange part. In the exemplary embodiment, the compressed edge along the side arrangement of desktop has the height of about 0.125 inch to about 0.25 inch, and table angle can include the height that height is at about 0.25 inch to about 0.5 inch. Compressed edge along the end of desktop can have the height of about 0.125 inch to about 0.5 inch. Therefore, the compressed edge of the table angle of desktop and/or end can than the big twice of compressed edge laterally or many times. If it is required, the height of the compressed edge at table angle can than laterally and/or the height of the compressed edge of end much bigger, for instance three times, four times, five times or many times.

Desktop can also include one or more accommodation part, is sized for and is configured to hold the miscellaneous part of desk, for instance crossbeam, cross bar etc. Such as, desktop can include being sized and configured to the accommodation part of holding supporting construction top. Desktop can also include the accommodation part being sized and configured to hold a part for lower limb when lower limb is in folding position. It addition, framework can include being sized and configured to be easy to one or more openings that lower limb is connected on desk. Such as, framework can include the opening on the top of end and/or the supporting construction being sized and configured to accommodation crossbeam. Shape according to framework and layout, the opening on framework can be circular or non-circular configuration. By making transverse tube extend through the opening on framework, lower limb can fixing with desktop be connected.

On the other hand, a kind of desk can include framework and the lower limb assembly be made up of relatively solid and durable material (such as metal, steel etc.). It is appreciated, however, that framework and lower limb assembly can be made up of the other materials with suitable attribute and characteristic. It addition, desk, framework, lower limb assembly etc. can have multiple arbitrarily suitable shape, size, structure and layout according to the required purposes of such as desk.

On the other hand, a kind of desk can include the desktop with multiple recess. The plurality of recess can be spaced closely together and can cover at least most of, substantially all or substantially whole of the lower surface of desktop. The plurality of recess is arranged in substantially uniform manner, and its center dant has substantially the same size, shape design, orientation and arranges. It addition, some recesses in the plurality of recess can separate less constant or uniform distance with adjacent recesses. Advantageously, recess can aid in and forms the desktop that intensity, rigidity and/or structural intergrity improve. If it addition, the substantial uniform interval of some recesses in the plurality of recess arranging in substantially uniform manner, then may consequently contribute to form the desktop with substantial uniform characteristic.

On the other hand, a kind of desktop can include being arranged proximate to and/or near the stiffener of the structural support members of desk or parts, for instance recess, rib, raceway groove etc. Such as, desktop can include contiguous and/or near frame arrangement multiple stiffeners. More specifically, desktop can include one or more framework accommodation part, it is sized for and is configured to hold the sidebar of framework and framework accommodation part can include multiple stiffener. When framework is connected with desktop, framework can cover all or part of of the stiffener in framework accommodation part. Stiffener in framework accommodation part can be arranged to different arrangement and/or structure, so can be used to form the region increasing intensity and/or different qualities. Such as, stiffener can be arranged in the first and second structures. Specifically, the first structure of stiffener such as generally aligns in a first direction along the direction of the length of desktop, and the second of stiffener the structure such as generally can align in second direction along the direction of the width of desktop. The first of stiffener constructs can provide the second of bigger intensity and stiffener to construct the intensity that can provide bigger in second direction or position on a direction or position. Owing to stiffener can provide extra intensity on different directions and/or position, relatively firm, solid, stable and/or rigidity structure so can be manufactured.

On the other hand, a kind of desktop can include having different configuration and/or be arranged in diverse location to prevent or to reduce the stiffener of the situations such as the weak spot, the stress concentration that likely occur. Such as, stiffener can be sized and configured to the region that supporting desktop is arranged in outside framework. Stiffener can also be sized and configured to contribute to preventing desktop from bending when load or power apply on the table, collapse folding or deflection. Additionally, stiffener can be sized and configured to contribute to preventing desktop from relative to framework distortion or rotating. Advantageously, because stiffener can aid in supporting desktop be arranged in the part above framework and/or'sTherefore desk that is firm, solid and that obtain effectively support can be formed. So further facilitate stacking with nested of desk, because the desk below such as in stacking desk is unlikely subject to stacking the damage of desk weight.

On the other hand, a kind of desktop can include being arranged in framework and hold part with the outer part of desktop such as between flange part and/or be connected the two one or more stiffeners. Specifically, one or more stiffeners can connect framework and hold part and flange part at least some of, for instance the inwall of flange part or sidewall. More specifically, one or more stiffeners can be at least partially disposed on upper surface and/or the sidewall of framework accommodation part, and flange part sidewall at least some of on. Owing to stiffener can make framework accommodation part be connected with flange part, therefore stiffener can improve intensity and/or the structural intergrity of framework accommodation part and/or flange part. Further, since framework can cover the sidewall of at least some of of framework accommodation part and flange part, therefore these stiffeners can generally be hidden.

On the other hand, a kind of desktop can include multiple stiffeners of being generally mutually aligned. Such as, these stiffeners can include each stiffener in the main body generally alignd and multiple stiffener with axis can along same or parallel to the axis and generally align. Advantageously, stiffener owing to generally aliging with axis can have the intensity of increase, structural intergrity and/or other features in particular directions, therefore makes stiffener can aid in, along same axis or the alignment that parallels to the axis, the desktop forming substantially uniform attribute and characteristic. Desktop can also include along other multiple stiffeners that coaxial line does not generally align. Such as, the stiffener arranged along not coaxial line can improve along the intensity of this axis, structural intergrity and/or other characteristics. Therefore, the stiffener arranged along not coaxial line can be used to form desktop and have the part of different qualities. So such as make some stiffeners being arranged in framework accommodation part can arrange along the first axle such as generally alignd with desktop length, and make other stiffeners can arrange along the second axis such as generally alignd with desktop width. If it is required, one or more stiffeners can be sized and configured to contribute to outward flange or the side of supporting desktop. Such as, stiffener can aid in and prevents the outward flange of the desktop not directly supported by framework from bending unintentionally, distorts or deflection.

On the other hand, the stiffener on a kind of desktop can include being arranged in desktop outward flange or flange part, for instance rib. Such as, desktop can include flange part or edge and can form multiple stiffener on flange part. Specifically, the inner surface of flange part such as sidewall can include multiple stiffener that extends internally. It addition, these stiffeners can be at least partially disposed in framework accommodation part. It is essential that stiffener can be arranged in the part above framework to a part for desktop such as desktop and desktop extends beyond intensity, rigidity, toughness and/or the structural intergrity that multiple parts such as flange part offer of framework increases. Advantageously, stiffener can also contribute to prevent desktop from undesirable bending, distortion or deflection occurring.

On the other hand, a kind of desktop can include having difformity, size, layout, orientation and/or the stiffener constructed and recess. Such as, the most of or substantially whole core of desktop can include the recess with substantially uniform shape, size, layout, orientation and structure. So can aid in and form the desktop with less constant characteristic. But, the side of desktop or edge can include recess or the stiffener with difformity, size, layout, orientation and/or structure. Such as, the edge of desktop can include the first group of recess generally alignd in a first direction and the second group of recess generally alignd in a second direction. If it is required, first direction is generally perpendicular to second direction, or angled with it, for instance 30 ��, 45 �� or 60 ��. Owing to recess or stiffener can align in different directions, therefore each several part of desktop can have different characteristics. The stiffener at contiguous desktop edge can also have different configuration. Such as, first group of stiffener can be arranged in framework accommodation part, and second group of stiffener can put framework hold part and flange part at least some of on. These stiffeners can be arranged in the part above framework and/or desktop extends beyond the part of framework by supporting desktop.

On the other hand, a kind of desktop can include the accommodation part in portion on the table, is sized for and is configured to hold the bonding part of the adjacent tables being in nested configuration. Hold part to be supported by the basifacial stiffener of table. Such as, stiffener can extend inward in flange part along the side of desktop and/or be arranged on the lower surface of desktop. The inside of stiffener can contact, engage or the inside of adjacent accommodation part has, to provide, the accommodation part increasing intensity, support, rigidity and/or structural intergrity. Advantageously, multiple desk is so made to be stacked together, because accommodation part can bear the bigger weight from nested desk and power.

On the other hand, a kind of desktop can include the recess of substantially uniform pattern, and these recesses are arranged on the multiple row generally alignd extending across desktop lower surface. Multiple raceway grooves that desktop can also align with recess in column on the lower surface. The lower surface of desktop can also include recess, is sized for and is configured to contained structure supporting member such as cross bar. The end of both sides and raceway groove that raceway groove can be arranged in structural support members recess can be arranged to the side of desktop or end. It addition, multiple recesses can be arranged in the bottom of raceway groove. Raceway groove and recess are sized and configured to the end of proximity structure supporting member and/or desktop and provide extra intensity, rigidity, structural intergrity and/or torsion resistance. More specifically, raceway groove can align with recess in column and raceway groove can have different length. The width of the recess that the width of raceway groove can be essentially equal on desktop lower surface. Recess on raceway groove can have substantially the same shape, structure and layout with the pattern of the recess on lower surface, but has less size. Recess on raceway groove can be arranged in and the substantially the same pattern of the recess on lower surface, layout and spacing, so can provide minimum to the support of desktop upper surface or not have any impairment. So that desktop can have substantially uniform characteristic, for instance intensity, rigidity, structural integrity and/or torsion resistance.

On the other hand, a kind of desk can include the combination of the such as content such as said one or multiple feature, aspect. Such as, desk can include the framework with bonding part, and described bonding part is sized and configured to be arranged in the one or more accommodation parts in adjacent tables when desk nests together. Desk can also include the compressed edge being sized and configured to be arranged in the accommodation part on adjacent nested desk. Thus, framework and compressed edge can so that desk be directed at and be nested into stacks structure. In addition, desk can include being arranged in the recess below a framework part such as sidebar, and recess is sized and configured to improve the intensity of part, rigidity and/or the structural intergrity that desktop is arranged in above framework and/or the part of contiguous framework and desktop are not directly supported by framework. It addition, desk can include the recess relative to the angled layout of desktop lower surface. Such as, desk can include the recess in lower flange portion or sidewall, and these recesses are vertical relative to the lower surface of desktop or angled layout. It addition, desk can include so that when using or the storage table period of the day from 11 p.m. to 1 a.m can expose and be easy to see the opening of a part or the recess of framework, and at end and the opening forming handle.

On the other hand, a kind of desk can be made up of one or more materials and technique. Such as, desktop can be made up of molded plastics such as blow molded plastic. Framework and/or lower limb can be made up of High-Strength Low-Alloy (HSLA) steel rather than conventional carbon steel. It is essential that HSLA steel can than the carbon steel light 20% to 30% with same intensity. Therefore, the desk being made up of HSLA steel can be lightweight and have the intensity identical with the conventional table that carbon steel framework is made because with the HSLA steel that can adopt more small dimension. It is for instance possible to use desk made by the HSLA steel of 16 or 18 specifications less than conventional steel. But, HSLA steel is adopted in this industry or other relevant industries, because they are expensive more than conventional steel. It is to say, HSLA steel is subject to cost restriction. But, the minimizing of the amount manufacturing the HSLA steel needed for having the desk of one or more feature disclosed herein is enough to make up the price of more expensive HSLA steel or confirm its reasonability. Specifically, the amount owing to forming the steel with disclosed feature is considerably less than the amount forming the steel needed for corresponding conventional desk, and therefore HSLA is no longer influenced by cost restriction. As such, it is desirable to less steel and/or HSLA steel are firmer and lighter, HSLA steel making desk therefore can be utilized.

On the other hand, a kind of desk can include the lower limb with the supporting member component at remote interval, so can aid in formation and is unlikely to occur undesirable movement or the firm desk waved. Desk can also include having multiple variously-shaped, size, structure and arrange the desktop of the shapes such as such as rectangle, square, circle, rectangle. It addition, desktop can include one or more opening so that handle or handgrip are exposed and/or formed to a part for such as framework.

Framework holds part 74 and can be integrally formed on the lower surface 68 of desktop 12 as a part for unitary one-piece construction.

Stiffener 72 can be clipped in or be arranged between the upper surface of sidebar 42,44 and the upper surface 62 of desktop 12. Such as, stiffener 72 can include the opposite side of the upper surface one end arranged and the upper surface 62 contacting desktop 12 of contiguous sidebar 42,44. Stiffener 72 can also be sized and configured to be easy to air flowing in molding process, this point is especially advantageous when desktop is made up of blow molded plastic, because framework holds part 74 and can extend internally from the lower surface 68 of desktop 12 and there is limited space between the top and the upper surface of desktop 12 of framework accommodation part.

It will be seen that stiffener 72 can be arranged on the upper surface 76 of framework accommodation part 74 in Fig. 5 and 7. Stiffener 72 can hold the upper surface 76 of part 74 from framework and extend to the upper surface 62 of desktop 12. As it can be seen, each framework that can be formed in stiffener 72 holds raceway groove or the rib of contact or adjacent upper surface 62 on the upper surface 76 of part 74, but stiffener can also be groove, breach, recess or similar setting. Stiffener 72 can be fully disposed in framework to be held between medial wall 78 and the lateral wall 80 of part 74 or is limited in framework and hold in the medial wall 78 of part 74 and lateral wall 80. Although stiffener 72 can have elongate length as depicted, but stiffener can also have other appropriate structuring, for instance the shape such as annular, circle, ellipse, rectangle.

Stiffener 72 can be suitably sized to, shape is suitable for and is constructed and arranged to provide the intensity, hardness and/or the rigidity that increase to desktop 12. Stiffener 72 may be utilized for forming the desktop 12 with consistent characteristic or quality. Advantageously, stiffener 72 can aid in supporting desktop 12 and is arranged in the part above sidebar 42,44, so can aid in and prevents desktop from undesirable sagging or other deformation occurring. Stiffener 72 is also prevented from desktop 12 and is arranged in the part above sidebar 42,44 and bends when load or power are applied in this part of desktop or the folding that collapses.

Being clearly shown that in Fig. 5 and 7, desktop 12 can include first group or multiple stiffener 72, and these stiffeners are substantially or entirely arranged in framework to be held on the upper surface 76 of part 74. Stiffener 72 can have elongate length, and it is arranged in a first direction, for instance is essentially perpendicular to the length of desktop 12 and holds between medial wall 78 and the lateral wall 80 of part 74 at framework. Stiffener 72 can have substantial constant or consistent interval, size, shape, structure and/or layout. It addition, stiffener 72 can be arranged along axis and/or be in plan-parallel structure, and the adjacent strengthening members that framework holds in part 74 can spaced less constant distance.

Desktop 12 can also include second group or multiple stiffener 82. Second group of multiple stiffener 82 can have substantially the same size, shape, structure and layout. Second group of multiple stiffener 82 can also the less constant distance in interval. As it can be seen, first and second groups of multiple stiffeners 72,82 can have difformity, size, structure and/or layout. Such as, stiffener 72,82 can be arranged to be in different angles, for instance at a right angle, or is in different directions. Such as, in this embodiment, if first group of multiple stiffener 72 generally aligns with the length of desktop 12, then second group of multiple stiffener 82 generally can align with the width of desktop. If it is required, stiffener 72,82 can replace from the stiffener in first group of multiple stiffener and between the stiffener in second group of multiple stiffener.

As best shown in figures 5 and 7, stiffener 72,82 can have different configuration. Such as, stiffener 82 can be extend across framework hold the width of part 74 and can be at least partially disposed at the rib on one or more sidewalls 78,80 of framework accommodation part or raceway groove. Align with flange part 20 if framework holds part 74, then stiffener 82 can also be formed on flange part, for instance on the medial wall 84 of flange part. Stiffener 82 can be perpendicular to the such as side 22, edge of flange part 20 or desktop 12 and arrange, and stiffener can be arranged to plan-parallel structure. Stiffener 82 can be sized and configured to contribute to preventing the part that desktop 12 is not supported by framework 36 from bending or distorting.

More specifically, stiffener 82 can be formed on the medial wall 78 that framework holds part 74 and stiffener can extend along a completely or only part for medial wall. Stiffener 82 can also cross over the whole width that framework holds the upper surface 76 of part 74. It addition, stiffener 82 can be formed on the sidewall 84 of the lateral wall 80 and/or flange part 20 holding part 74 at framework.

Being clearly shown that in Figure 5, stiffener 82 can have different size and structure. Such as, some stiffeners 82 can be greater or lesser. Holding on both part 74 and flange part 20 advantageously, because stiffener 82 can be arranged in framework, therefore stiffener can aid in and makes framework accommodation part be connected with flange part. Stiffener 82 can also provide the intensity, hardness and/or the rigidity that increase to these parts of desktop 12. Such as, stiffener 82 can improve desktop 12 and extends or arrange the part such as intensity of flange part 20, hardness and/or the rigidity beyond framework 36. It addition, stiffener 82 can be sized and configured to prevent flange part 20 from undesirable bending or distortion occurring.

Therefore, in one exemplary embodiment, first group of multiple recess or stiffener 72 and second group of multiple recess or stiffener 82 can be arranged between top 14 or the upper surface 62 of sidebar 42,44 and desktop 12. As it is shown in figure 9, sidebar 42,44 can include top or upper surface 86, the lower surface 68 of this upper surface desktop 12. It addition, multiple stiffeners 72 can be arranged between the top of sidebar 42,44 or the first side 88A of upper surface 86 and the second side 88B.

Holding part 90 can be have groove or the raceway groove of certain altitude and width. Such as, the sidewall 106 holding part 90 can have the height of about 0.25 inch to about 0.5 inch, such as about 0.3 inch or 0.4 inch, and the lower surface 106 holding part 90 can have the width than highly big certain multiple, for instance twice, three times or more times. Such as, width can be the substantially twice of height so that in this illustrative embodiments, if being highly about 0.25 inch, then width can be about 0.5 inch. Height and width can also be roughly equal. Such as, if height is about 0.5 inch, then width can also be about 0.5 inch. It will be appreciated that width can also be less than highly. If it is thus possible, for instance be highly about 0.4 inch, then width can be about 0.3 inch or less. It will be appreciated that the height of accommodation part 90 and/or width can change according to the required purposes of such as desk 10.

Hold part 90 to be supported by the stiffener of bottom 16 and/or recess 94 being arranged in desktop 12. Such as, as shown in figure 11, stiffener 94 can include contact with the inside 98 (such as inner surface) holding part 90, the inside 96 (such as upper surface or inner surface) of adjacent or joint. More specifically, stiffener 94 can be inside or horizontal-extending relative to the bottom 16 of desktop 12. Such as, stiffener 94 can be arranged along the side 22 of desktop 12 and/or end 26. Specifically, stiffener 94 can be arranged on the medial wall 84 of flange part 20 and have the structure of generally bending or arc. The inner surface of stiffener 94 can contact the inside 98 holding part 90 in spaced apart with the outer wall of flange part 20 and stiffener inside 96. Desk 10 for about 6 feet of length, it is possible to 32 stiffeners 94 are arranged in each side 22 along desktop 10. Will recognize that, it is possible to arrange extra or less stiffener 94 according to the length of such as desk 10 or required purposes along side 22 and/or the end 26 of desktop 12.

As shown in Fig. 4-7 and 10-11, for instance, stiffener 94 can be arranged in the sidewall 84 of flange part 20. Stiffener 94 can also be arranged in an angle 24, for instance shown in Fig. 2 and 12. Advantageously, stiffener 94 can also be made up of recess or be called recess. Additionally, as mentioned below, one or more recesses may be used for connecting accommodation part 90 and stiffener 94. Will be consequently realised that, according to disclosed herein, stiffener 94 can depend on that the required purposes of such as desk 10 has difformity, size, structure and layout.

In different configuration and layout, stiffener 94 can also be arranged to other angles and/or be connected with the inside 98 holding part 90. Such as, as shown in figure 12, stiffener 94 can be arranged on the table angle 24 of desktop 12. Stiffener 94 on table angle 24 can upwardly extend from the lower surface 68 of desktop 12. More specifically, the inside 96 of the stiffener 94 on table angle 24 can contact, adjoin or engages the inside 98 holding part 90. Specifically, the inside 96 of stiffener 94 can contact the inside 98 holding part 90, for instance the inner surface of bottom 100 and/or the inner surface of sidewall 102. Each the angle 24 of desktop 12 can include 8 connecting portions between stiffener 94 and accommodation part 90. Will recognize that, desk 10 can have any an appropriate number of connecting portion between stiffener 94 and accommodation part 90, and stiffener can be arranged in any suitable part of desktop 12 and stiffener can have other sizes, shape, structure and layout according to the required purposes of such as desk 10.

Advantageously, intensity, support, hardness and the structural intergrity that stiffener 94 can increase for holding part 90 to provide. Stiffener 94 also makes accommodation part 90 can support sizable weight or power. It is essential that a large amount of desk 10 so can be made to arrange be in nested configuration, will not be destroyed by the weight of desk because being such as arranged in the desk stacking structure bottom. Such as, when desk 10 nests together as shown in Figs. 13 and 14, bonding part 92 can contact or adjoin the lower surface 104 and/or sidewall 106 that hold part 90 and they can become load-bearing surface. Owing to stiffener 94 can improve the accommodation intensity of part 90, rigidity and/or structural intergrity, therefore so considerable desk 10 can not had holding to stack and nest together under the premise that part generation destroys.

One or more recesses can also support accommodation part 90. Such as, one or more recesses can make stiffener 94 be connected with holding part 90. It addition, one or more recesses can be formed on the bottom 14 of flange part 20 and/or desktop 12, and recess can contact, engage or the adjacent inside 98 holding part 90.

Desk 10 can also include other structures improving the intensity of desktop 12, hardness and/or structural intergrity. Such as, the lower surface 68 of desktop 12 can include one or more recess 110, is sized for and is configured to contained structure supporting member, for instance a part for supporting construction 28, framework 36, crossbeam 38, crossbeam 40 and/or crossbeam 52. Such as, as shown in figure 16, first crossbeam recess 112 can be sized and configured to hold a part for crossbeam 38, and second cross beam recess 114 can be sized and configured to hold a part for crossbeam 40. 3rd crossbeam recess 116 can be sized and configured to hold the crossbeam 52 of the center arrangement of contiguous desktop 12. The lower surface 68 of desktop 12 can also include the first supporting construction recess 118 and the second supporting construction recess 120, and they are sized and configured to hold and are in folding or storage position supporting construction 28. Recess 112,114,116,118 can by making the bottom that the top of adjacent one another desk is arranged in a desk be easy to the nested of desk 10 with 120. Recess 112,114,116,118 and 120 can also contribute to multiple positioning parts in desired location.

The lower surface 68 of desktop 12 is additionally may included under plan-parallel structure one or more raceway grooves 122 of alignment. The width of the recess 60 that the width of raceway groove 122 can be essentially equal on lower surface 68, and raceway groove is preferably directed at recess. Advantageously, because raceway groove 122 can be directed at recess 60 and have substantially equal width, therefore raceway groove can not interfere with or interfere pattern or the arrangement of the recess of substantially uniform layout. However, if it is desired to, raceway groove 122 can have the width more greater or lesser than the width of recess 60.

As shown in figures 15-19, multiple recesses 124 can be arranged in raceway groove 122 bottom 126 and recess can contact, adjacent or engage the upper surface 62 of desktop 12. Recess 124 can have identical aggregate model, interval, size, shape, structure and layout. It addition, the recess 124 on the bottom 126 of raceway groove 122 can be arranged is in the pattern substantially the same with the recess 60 on lower surface 68. If it is essential that recess 60,124 is arranged is in substantially the same pattern, then the desktop 12 with substantially uniform characteristic such as intensity, hardness and structural intergrity can be formed.

Raceway groove 122 can have various different length. Such as, some in raceway groove 122 can have recess 124 such as 3 length being arranged on bottom 126 only making limited quantity. Other raceway grooves 122 can have the longer length making greater number such as 10 or 12 recesses 124 be arranged on bottom 126. Additionally, other raceway grooves 122 can extend to the other end from one end of desktop 12. Will recognize that raceway groove 122 can have any suitable length.

Raceway groove 122 can be suitably sized to, shape is suitable for and is constructed and arranged to improve the intensity of desktop 12, hardness, structural intergrity and/or torsion resistance. Such as, raceway groove 122 can have opposite wall 128,130 and described opposite wall can improve the intensity of desktop 12, rigidity, structural intergrity and/or torsion resistance. The bottom 126 of raceway groove can also be spaced apart adjacent upper surface 62, and can improve the intensity of desktop 10, rigidity, structural intergrity and/or torsion resistance.

Raceway groove 122 is preferably placed in the both sides of structural support members such as crossbeam 38,40. Specifically, raceway groove 122 preferably extends through crossbeam recess, for instance the first and second crossbeam recesses 112,114, and through the both sides of crossbeam recess. It addition, recess can be arranged in the cross part of one or more raceway groove 122 and crossbeam recess. It addition, the end of raceway groove 122 part that preferably contiguous desktop 12 is not directly supported by framework 36 is arranged. Such as, the end of raceway groove 122 can be close to the end 26 of desktop 12 and arrange, described end 26 extends beyond sidebar 42,44 and the end of crossbeam 38,40. Specifically, the first end of each raceway groove 122 in multiple raceway grooves can be arranged proximate to the first end of desktop, and the end of raceway groove can and the first end generally interval equidistance of desktop. Raceway groove 122 can also have different length. Advantageously, raceway groove 122 and recess 124 can improve near structural support members and adjoint recess and the intensity of end 26 of desktop 12, hardness, rigidity and/or structural intergrity. It is essential that be so possible to prevent the end 26 of desktop 12 to be rotated down relative to the end of crossbeam 38,40 and/or framework 36 or mobile, the torsion resistance of desktop 12 so can be improved.

In figs. 18 and 19 it will be seen that lower surface 68 can and the less constant distance in upper surface 62 interval so that desktop 12 has less constant height or thickness. It is arranged in the various structures on the lower surface 68 of desktop 12 and can have different height. Such as, crossbeam recess 112,114,116 can have the height of the thickness being slightly less than desktop 12. Framework holds part 74 can have the height less than the height of the thickness of desktop 12 and crossbeam recess 112. The bottom 126 of raceway groove 122 can also have the height less than the height of the thickness of desktop 12 and crossbeam recess 112. As it can be seen, the height that framework holds part 74 and raceway groove 122 can be roughly equal. Therefore, the height of crossbeam recess 112,114,116 can hold between the height of part 74 and raceway groove 122 at framework. Hold part 74 due to framework and raceway groove 122 highly can be roughly equal, and framework accommodation part can include stiffener 72,82 and raceway groove can include recess 124, therefore the upper surface 62 of desktop 12 can have generally similar characteristic, for instance intensity, rigidity and structural intergrity.

In this illustrative embodiments, the upper surface 62 of desktop 12 can generally obtain even support, so makes desktop can have less constant characteristic and quality, for instance the intensity of upper surface, rigidity, structural intergrity and smoothness. will recognize that, desk 10 and desktop 12 can also have other suitable feature, aspect, structures etc., the name such as submitted on April 24th, 2012 the applicant is called the U.S. Patent application 13/455 of " TABLEWITHMOLDEDPLASTICTABLETOP (has the desk of molded plastics desktop) ", the name that No. 073 (agency reel number L1006.10612US01), on April 24th, 2012 submit to is called the U.S. Patent application 13/455,081 (agency reel number L1006.10614US01) of " TABLETOP (desktop) ", and and the name submitted on April 25th, 2012 of the applicant be called the Chinese invention patent application (agency case M0141-00044) of " desk with nested desktop ", the name that on April 25th, 2012 submits to is called the Chinese invention patent application (agency case M0141-00046) of " framework of desk ", the name that on April 25th, 2012 submits to is called the Chinese invention patent application (agency case M0141-00048) of " desk with molded plastics desktop ", the name that on April 25th, 2012 submits to is called the Chinese invention patent application (agency case M0141-00052) of " desktop ", the name that on April 25th, 2012 submits to is called shown in the Chinese invention patent application (agency case M0141-00054) of " desk ". these apply for each leisure, and this is fully incorporated as reference.
